I'm on a Mac, running Catalina, with 64 GBs of RAM, and Firefox is using about 20+ GBs of RAM, and very high CPU usage. I keep trying new updated versions, hoping this will no longer be an issue, but it persists. Is there anything I can really do, to tamper it down?

I tried opening FF in safe mode, only to find several windows with several tabs on each GONE! Why should troubleshooting issues only make me more frustrated and ready to can this browser forever? Help should be help, not making things worse...

Well, this forum is pretty useless, most questions going unaddressed. And we can't even send feedback to the FF developers, first time I've seen a browser with no feedback option, are they sleeping?

Now Firefox is using 24 GIGS of RAM... Seriously??? Pages won't load, or take forever doing so, forms can't be sent in from websites, streams constantly stopping for buffering, what a mess this formerly reliable browser has become..... smh
